After Germany invaded France in May 1940, Mussolini, expecting a swift German victory, cynically declared war on France and Britain on 10 June 1940. His troops invaded France ten days later. After its defeat, France signed an armistice with Germany on June 22. A Franco-Italian armistice was signed on June 24. Italy then annexed part of Menton, in South East France, and also established a small occupation zone that included Nice and Grenoble.
In October 1940 Mussolini invaded Greece, but by November the brave Greeks had the Italians on the back foot. Hitler intervened with a blitzkrieg occupation of Greece and also Yugoslavia, but to do so he had to postpone his planned invasion of Russia. Mussolini gained Dalmatia, most of Slovenia, and established a protectorate over Montenegro, but Italy did not issue any special coinage for these new conquests and annexations.
